[cairo] scaling a surface

I'm sure this is trivial, but for some reason I can't get it to work.
Basically I have a graph that I want to start to shrink in the x direction
when the data reaches the right side of the graph. My idea was to use a
buffer so that the following would occur (based on a graph width of 100).
if data_x> 100
copy surface to buffer
shrink buffer surface so that it is 99 wide
copy the buffer back to the surface
cairo_move_to(cr , 99,y_prev);
obsiously the 99 will also have to be properly scaled so that it has the
same scaling as the other data so I will have to keep tabs on how many times
the data has been scaled.
Hope someone can come up with an idea..
